THE
PROSOBRANCHIA OF THE SIBOGA EXPEDITION
PART II
TAENIOGLOSSA and PTENOGLOSSA
PART II
TAENIOGLOSSA and PTENOGLOSSA
This part contains the enumeration of about 340 species, of which 39 have been
described as new to science, moreover a few varieties have been described and partly figured.
By comparing these numbers to those of the first part, it is evident that this first part was
more interesting, the groups now under consideration not being composed of so many deep
water forms, and it is amongst those, as might be expected, that the most interesting species
are to be found, as for instance in the genera Morio, Oocorys, Segaenzia.
I have to thank again Mr. E. A. Smith for his assistance in comparing doubtful species
also Messrs. J. Cosmo Melvill, Pii. Dautzenberg, E. R. Sykes and others, for assistance, loan
of specimens or litterature.
I must repair a few errata in the first part, which I discovered in returning the materials :
p. 10. var. strigillata belongs to N. turrita not to variegata.
p. 13. the Ncritilidac must follow after Septaria, which belongs to the Neritidae.
p. 71. for Euchchts iutricatus Gould read Etich. instrictus.

Kesteven (Proc. Linn. Soc. N. South Wales, 1902, p. 476) says that according to Hanley,
(Ipsa Linnaei Conchylia, p. 2871 the name pilearis should be applied to the Mediterranean
Triton corrugatus Lam., and that tin- species under consideration should bear the name aquatilis
Reeve, uniting it. in accordance with Tryon etc. with aquatilis. As Linné says: "Habitat in M.
Mediterraneo", this view may be in so far right. But Troschel (Gebiss der Schnecken I, p. 234)
d small differences in the radulae of Simpulum pilearis Liri. (1. c. PI. 20, fig. 3) and
iquatile Reeve d.c. PI. 20, fig. 4) so I have left the name pilearis to the species generally
known under this nomination.

The specimens from Lamakera and Bima are quite typical, corresponding to Reeve's

some varieties of the preceding species, but there the dark colour occupies the interstices of
the spiral lirae, whereas in the specimen of gemmatus the dark colour runs over the lirae. In
sculpture I see no difference with the other specimens.

The only specimen is still young, but perfectly agrees in sculpture with the upper whorls
of an adult specimen from the Philippines. Tryon considers it to be the same as T. lotorium
Lin., he says: "the distinctive characters are individual only". As far as I can judge, I think
the differences of sculpture are sufficiënt to separate them specifically. The young shell is covered
by a thin epidermis with long bristles on the radiating ribs and varices.

The specimens from Stat. 116 and 285 are young and have a somewhat misleading
appearance, by the closer sculpture. Ilowever the species is very variable in this respect, and
these specimens are connected t<> more typical ones by intermediate forms, I. i. those from
Stat. 313. Tryon says on this. subject (1. c. p. 43): "The tubercles are numerüiis on the earlier
whorls, bnt in some instances) coallesce into two large ones between the varices on tlie last
whorl of the adult. When the more numerous tubcrcles are persistent, the resemblance to the
R. tuberculata) is striking".

The specimen from Stat. 315 is young, but agrees sufficiently with the other specimens
to be identified. The long and slender radula, has the teeth in about 108 transverse rows.
The rhachidian tooth (R) has a subquadrangular body with the sides strongly excavated in the
posterior half, posterior margin much shorter than the anterior one ; the cusp has 5 denticles,
of which the median one is the largest; the lateral tooth (1) has an oblong shape with a large
denticle on the proximal side of the cusp and three smaller distal ones; the uncini (U) are
hooked, slender, the first one with a small denticle on the proximal side, only visible by the
transparency of the teeth. The construction of the radula, proves that Dall, in his paper (An
historical and systematic review of the Frog-shells and Tritons; Smiths, Miscell. Coll. Vol. 47, 1905,
p. 114 — 144) is right in calling the species united as Gyriiiauit, the nearest allies of Aquillus.
He mentions only the radula of Ranella (Apollon) argus Lam., described by Troschel, (Gebiss
der Schnecken, Vol. I, pi. 20, iïg. 11) which is conchologically a somewhat peculiar species;
really the radula now under consideration, shows more resemblance to those of Tritonium
femorata Lin. (1. c. fig. 2) and of T. pilcarc Rve (1. c. fig. 3), the most typical difference being
the narrow posterior basal margin.

This species is very variable in colour and also in sculpture; the specimen from Stat. 144
is yellow, and has the spiral lirae scarcely developed on the lower whorls ; if this character be
not individual, it might give right to a vanetal name.

1 Inly one broken shell, which agrees in every respect with my specimen from Torres-
strait. Tryon lias only mentioned it in his register, as a synonym of G. perca, but not in his
systematic enumeration. Boog Watson in his " Challenger"-Gastropods, has mentioned it (p. 402)
also as a synonym. E. A. Smitii (1. c.) and Brazier have separated it, I think on sufficiënt
groufids. Indeed, if one compares the shells, they are very different; with the same number of
whorls, the shell is still much smaller, than the var. aculeata of the preceding species, and has
the tubercles on the whorls still more numerous, the varices are impressedly striate, not ribbed,
with broad interstices, as in G. perca.

The specimen from Stat. 50 is white, with a few brown spots and a yellow margin of
the aperture, but agrees in other respects. I must doubt if the figures of the Conchylien-Cabinet
really belong to this species, notwithstanding the statement that they had been erroneously
united to B. albivaricosa. I think the canal resembles much more in shape that of Bursa rana
(albivaricosa) than that of B. margaritula, which is much shorter and in the back view is
directed to the left.

The specimen from Stat. 251, which is a dead, broken shell, differs from the other
specimens in sculpture, the beads being larger, the spines on the body and varices smaller, it
is also slightly different in shape; as however Mr. E. A. Smith declared it to be merely a
variety of B. rana I have left this single specimen under that species.

'lobosely ovate, moderately ventricose, rather strong, white under a yellowish
epidermis; whorls about 5 , (nucleus ones worn) convex, with a distinct suture and with strong
of which there are six on the penultimate whorl; 22 on the last one, including the
eparated l>y interstices, with a few exceptions about as broad as the
themselves, the uppermost liration borders the suture and is separated from the second
by a broader concave interstice, giving it a channellike appearance; the interstices and in
ree the lirae, are crossed by radiating striae, which are coarser on the upper whorls.
Aperture oblong-ovate, angular above, ending in a broad canal directed towards the left,
columellar margin with a rather strong layer of enamel, spread over the bodywhorl; it is
grooved by the lirae and covered with microscopic granules-, columella rounded, curved, strongly
bent to the left along the canal; right margin nearly regularly curved, with an angle, corres-
ponding to the second lira, and with an external rib, expanded and grooved interiorly; these
grooves extend in the interior of the shell, which is porcellaneous.

This species is less globose than O. sulcata Fischer (Journ. Conch. 1883, p. 392) with
fewer lirae (6 in the penultimate whorl, instead of 8 to 12) the radiating striae seem to be
much weaker than in sulcata, at least than in the "Challenger" specimen, where the interstices
are much broader (Boo<; Watson: "Challenger" Gastropoda, PI. 17, fig. 11). In Benthodolium
(= Oocorys) abyssorum Yerrill (Transact. Connecticut Acad. Vol. VI, 1882 — 85, p. 177, PI. 31,
fig. 1 2 i the spire is much higher if compared with the aperture, the lirae are much more
numerous, and the interspaces much broader, the canal much straighter. It appears rather
doubtful to me, that these specimens should belong to the same species, unless it be exces-
si vel y variable. 1 think the differences enumerated above, will be sufficiënt to separate shells
of such a remote provenience.

haracters to separate it from the atlantic species, described by FlSCHER, it agrees
far as may be judged from the description and Fischer's figure, which is
12 I
only a woodcut; the small differences may be individual; the number of spiral lirae described
by the author, as being from 8 — 12, are at least 12, perhaps 13; the most striking difference,
the simple peristome, is probably valueless, as it depends without doubt on age. E. A. Smith
(Ann. and Mag. of Nat. Hist. Ser. 7, Vol. 17, 1906, p. 170) mentions a specimen under the
name of var. indica, with the locality "off S. of Ceylon, 191 2 fath." which cannot be separated
specifically from the species under consideration.

2 Spec.
Shell elongately-ovate, rather strong, white under a yellowish epidermis; spire rather
high; whorls 5, (nucleus wanting) convex, with an impressed suture and strong spiral lirae, 10
to 12 on the penultimate whorl, from 25 to 32 on the last one, they are separated by inter-
stices which are in most cases broader than the lirae; the whole shell (lirae and interstices) is
crossed by radiating striae. Aperture oblong-ovate, angular above, ending below in a very short,
wide canal, slightly directed towards the left, columellar margin covered by a layer of enamel
spread over the bodywhorl, it is grooved by the lirae and microscopically granular, columella
rounded, slightly curved, strongly bent to the left, along the canal; right margin regularly
curved, slightly expanded but not ribbed exteriorly, thickened and grooved interiorly; aperture
porcellaneous. A small umbilical slit, may disappear with age.
Operculum typical, reddish-yellow, with a shallow groove at the right margin.
Alt. 2,-^1^ lat. 221/.,; apert. alt. 21 (incl. perist.) lat. n1/,.
This species di fiers from O. sulcata, in being much more elongate, with a higher spire,
the aperture being about i1/., X as long as the spire, being nearly 2 X as long in O. sulcata,
even the more elongate figure of the "Challenger" specimen, is still shorter, and has also a
shorter spire in proportion. Benthodolium abyssorum Verrill, which agrees in this respect, is a
much more ventricose shell, with much broader aperture. The two specimens vary in sculpture
as stated above, that of the smallest specimen being considerably finer; the upper whorls of
this specimen are strongly eroded and the last whorl seems to have been broken, at least at
some distance from the thin margin an irregular varix makes its appearance, and the umbilicus
is more open. I think however these differences between the two specimens, will prove to be
individual and in part accidental.

1 cannot agree with Tryon's opinion, that this and the preceding species are only varieties
of C. saburon Adans., the species now under consideration, ma)- be easilv distinguished by its
last whorl, which is smooth, with exception of the grooves at the upper and basal parts, instead
of being spirally striate as in C. pila and saburon, which may on their turn be distinguished
from each other, by the lower part of the columella, which is closcly plicated in C. pila, as
K ster (1. c.) has observed, moreover by closer striae on the bodywhorl of that species.

Shell globosely-ovate, ventricose, with a raised, conical spire; white, with a yellowish
epidermis; whorls about ó1/», the upper part of the smooth nucleus wanting, the whorls are
convex, separated by a deep suture, spirally striate and lirate, the upper ones moreover with
obtuse ribs; on the lower whorls the infrasutural liration is strong, divided by a groove, more
below the lirae are still stronger and granulose, and number from one on the fourth whorl, to
two and three on the penultimate one; these 3 principal lirae are persisting on the last whorl,
where they bear about 30 granules, and are succeeded towards the front part of that whorl,
by eight granulose lirae, which become however weaker in approaching that iront part and
are finally succeeded by about 12 nearly smooth lirae; the 3 principal lirae are divided by 2
grooves, and a few of the other ones by a single groove, moreover many of the interstices
are provided with much smaller lirae, from one to three in number in each interstice; the whole
shell is crossed by conspicuous growth-lines. Aperture oblong-ovate, angular above, terminating
anteriorly in a short, slightly recurved canal ; columellar margin callous, with rugose plicae,
corresponding to the lirae, columella rounded, nearly straight, obliquely truncated, its left margin
slightly expanded, leaving only a scarcely visible umbilical slit; outer margin thickened, riblike
124
rnally, flattened and obscurely denticulate internally, slightly angular at some distance from
its upper part, where it joins the body-whorl.

the body-whorl, not loosened like in echinophora, the labial rib is much stronger, the sculpture
more delicate, the shape more pyriform, etc.

it is white with light brown lirae. Whorls abont 8, of which 41/, form the smooth, yellow nucleus;
t hi- other whorls very convex, with a conspicuous suture and rather strong spiral lirae, about
16 principal ones on the last whorl and smal] intermediate ones, which are of a still lighter
colour, moreover 5 lirae on the canal; after a few thinner lirae below the suture, 9 of the
principal lirae are more or less granulose on the dorsal part of the whorl ; the shell is crossed
by numerous, rather conspicuous, lamellose or riblike striae, which run over the lirae, and very
fine growth-striae. Aperture oblong-ovate, angular above, ending below in a short, broad, only
slightly recurved canal : columellar margin with a very thin layer of enamel on the bodywhorl,
slightly stronger below, on the nearly straight columella, which is slightly oblique near the
canal. leaving a very small umbilical slit, nearly closed by the layer of enamel: outer margin
larly curved, exteriorly with a conspicuous rib, which is flattened and rather strongly
denticulate interiorly. Interior of aperture with grooves, corresponding to the external lirae, the
grooves light brown.
Alt. 411,',. lat. 297.; apert. alt. (incl. canal) 28, lat. 121/, Mill.
This species is allied to the preceding one, but the shell is smaller, thinner, more
ventricose, the granules on the brown lirae are weaker and not divided by spiral striae, the
canal is shorter, less recurved, the ventral side and columella nearly without enamel.

The suggestion of Mr. J. Brazier, that this species should live in deep water, has not
been confirmed by the collection of the Siboga-Expedition. The specimens vary considerably in
colour-pattern, that from Stat. 77 is much bleached, those from Stat. 99 have a broad brown
band in the centre of the back, bordered by narrow zones of a light colour and a few spiral
rows of brown blotches. A very young specimen from that locality, with scarcely any traces of
teeth, is uniformly brown on the back, whitish near the produced spire and along the right
margin of the aperture; those from Stat. 109 have but a few brown blotches near the dark
central band (broken up in one specimen), that from Stat. 1 64 has only a single indistinct band ;
the specimens from Stat. 3 1 3 are very similar ; these differences seem to be only individual,
I have failed to recognize one of the described varieties amongst them.

I have foliowed the quoted authors in occupying the name flavcola Lin. for this shell ;
Weinkauff (Mon. Cypraea, p. 103) says that it should be only a variety of C. gangrenosa,
and that the true C. Jïaveola Lin., might be a small variety of C. spurca Lin. It is no doubt
nearly alliecl to the next species.

Though I must admit that the characters of the radnla are often insufficiënt to decide
upon the specific value of species, the differences between the radula of the species under
consideration and the preceding one, seem to be of too much importance, to consider them
as varieties "I" one and the same species. It would be interesting to examine the radulae of
mens which conchologically are intermediate, aml to make out, to which of the two forms
the nearest allies.

In the original description SoWERBY says : "sulco dorsali nullo ant inconspicuo"; TRYON
has located tin- species in his section without dorsal impression. In consequence I cannot agree
with tin- view that Cypraea pilitla Kiener should be a synonym; KlENER says that the dorsal
impression is rather deep in his species. WEINKAUFF (Conch. Cab. lul. 11, Cypraea, p. 1501 says
also, dealing with C. pilula: "linea dorsali impressa" and adds in a footnöte that the lithographer
forgotten it in the figure. The Siboga-specimen has a very shallow impression, much less
picuous than the specimen of the former species.

Shell ovate, moderately inflate, white, pellucid, right margin thickened, extremities slightly
produced, especially the anterior one, with rather numerous ribs, of which the majority runs
from one side to the other and a few intermediate ones, no dorsal sulcus. Aperture rather wide,
especially tovvards the front, slightly arcuate, its right margin but little inflected, thickened
exteriorly, strongly crenulated by the ribs, which form from 1 8 to 21 teeth ; anterior sinus wide,
posterior one narrower by a crenulated callus, columellar margin not thickened, with about 20
teeth, the interstices of the ribs of both the right and columellar margin granulous, the inter-
stices on the back smooth.

The species resembles amongst the white ones without dorsal impression, in some respects
T. pellucidiila Gaskoin, which has however much more and finer ribs. One of the specimens
from Stat. 105 contains the soft parts and may serve as a proof that the species lives at the
recorded great depth.
6. Trivia pcmcicostata n. sp. PI. XI. fig. 2.
Stat. 95. 5°43'.5 N., ii9°4o'E. Sulu Sea. 522 M. Stony bottom. 3 Spec.
Shell shortly ovate, swollen, greyish-white (perhaps flesh-coloured in life), with few strong
ribs and rather wide, smooth interstices, considerably broader than the ribs; no dorsal impression,
the majority of the ribs runs from one side to the other, with a few intermediate ones which
don't reach the centre. Aperture rather wide, running on the right side of the ventral face,
slightly wider at the anterior end. Right margin relatively thin, with a thickened rib exteriorly
and only 13 teeth, columellar margin with about 14 teeth, slightly excavated interiorly, front
sinus large, posterior one narrower, with a small callosity on the left side, anterior end slighty
rostrate or produced ; interstices of the ribs on the apertural margins granose.
Long. S1/., lat. 63/4, alt. 5 7, Mill.
This and the next species resemble some of the South-African species by their aperture,
which lies on the right side of the base, and is larger than usually in Trivia. In sculpture,
but not in shape, it resembles T. Bitttoni Melv. (Ann. Mag. Nat. Hist. Ser. 7, Vol. VI, 1900,
p. 209) this species is however more regularly ovate in outline, the dorsal view of the new
species being subtrigonal, in consequence of the blunt posterior part, in Buttoni the aperture
is much narrower and is situated more centrally.

from Stat. 95 are stil] smaller, being only 7'/, MUI. in length, but agree
jn m ts, in sculpture with the type, however the ribs are slightly coarser, the teeth of
the right margin less numerous (15 and 17), the other specimens and that from Stat. 315 are a
doubtful, as they are still considerably smaller, length only 6 MUL, the aperture is not so
and the right margin thicker-, as they are dead shells, I prefer to keep them under one
name with the variety, instead of describing a new species on a few gradual dirferences. This
species with its variety, differs from the former one, by its much more numerous ribs with
numerous intermediate ones, the larger number of teeth and inflated shape.

The specimens are very small, that from Stat. 285 measures only 8 Mill. in length, that
from Stat. 98, which is the largest, 11 Mill.; this latter specimen, which may have been washed
down to that considerable depth, is bleached and shows only traces of striae on both extremities,
which are more distinct on the two other specimens; this latter character reminds A. ealedoniciim
Crosse, but that species has been described as "striated", without the restriction that this should
only be at the extremities. Now of the specimens under consideration, that from Stat. 98 is
nearly quite smooth, with only a few striae at the posterior extremity and perhaps one or two
at the anterior one, that from Stat. 285 has anterior and posterior striae and is smooth at the
central part of the back, and that from Stat. 2 has also a few indistinct striae on the back,
but it is not decussated, as it should be in A. ealedonicum, nor can I detect brown spots on
the back, for the spots I see on the last-named specimen, seem to be accidental.

Shell small, pyriform, strongly angular on the back, the extremities elongate, thin,
transparent white, with rose-coloured, irregular spots, arranged in three bands, one near the spire,
one near the centre before the angle, the third near the anterior part, moreover the extremities
are rosetinted. Sculpture consisting of rather broad, waved, impressed striae, which are shallow,
but at least half as broad as the lirae, they are crossed by fïne growth-striae, which are partly
^tnmger, so as to render the surface here and there cancellated; the angle is placed on the
posterior half, the shell is rapidly contracted towards the posterior part, regularly contracted
towards the anterior part. Aperture narrow, angular, with a short canal at both extremities;
outer margin thickened, with numerous fine teeth on the front part, much stronger towards the
spire, where they cross the thickened margin and render it crenulate on its external margin,
3 visible in the dorsal view; columellar margin with a crenulate callus behind, a fold borders
the front canal. this margin is excavated internally; a thin layer of enamel covers the columellar
of the shell.
Long. 83 „ lat. 5 Mill.
This species is nearly allied to A. concinnum, but differing in many particulars, the shell
angulate, more rapidly contracted towards the spire, a line from the angle of the

The three specimens are slightly different from each other, the smallest agrees with the
original description, being small and white, however with orange-coloured extremities (perhaps
Sowerby's specimen was a bleached one), the other adult one is larger but agrees with the
descriptions of Reeve and Weinkauff, the thircl is a young shell, with a thin right margin ;
its colour is white on the ventral side, light orange-red on the back, with 3 white bands;
perhaps this depends on age. I can see no reason to distinguish this juvenile specimen by a
new name, only on partly different colour.

The specimen from Stat. 310 is still very young and ;i little doubtful, those from
273 are fine and adult. I think Tryon has gone too far in uniting so many species to
A. philippinarum, so I have recorded the two next forms as separate species.
The radula is long, yellowish-brown and consists ut a large number of transverse rows
>■{ teeth. The rhachidian tooth (R) has a broad sub-quadrangular body with convex upper and
basal margin, a long sharp median denticle and 3 smaller ones on each side, the laterals (1) have
an elongate body ending in a tail on the distal side and a tricuspid cusp, composed of a very
large central denticle and a small one on each side, the uncini have the ordinary comblike
structure, the inner one has 15 denticles, of which the majority is simple, only a few <>f the
distal ones and sometimes one or two others are bifid, the denticles of the outermost of the
uncini are as a rule bifid, in a few I see three cusps, the number of denticles is about 40, with
a knoblike one at the distal extremity.

The specimen \v<>\n Stat. 164 is a dead shell with impressed striae over the whole surface,
this niay however depend on the circumstance that the shell is slightly worn, as I see traces of
striae in a fresh but young specimen from Stat. 273. The shell is in comparison much narrower
than the preceding one, the shape is more elegant, in fresh specimens the tips are slightlj rosy.
The radula resembles in many respects that of the former species. The rhachidian tooth
1 sub-quadrangular body, with a long median denticle and two smaller ones at each
1 | with their tailed body, have also a long cusp with one smaller denticle
rr, two very small unes on the outer margin. The uncini are comblike, with usually
few bifid denticles amongst the inner om-s and bi- and trifid in the outer ones.

As far as may be judged from a single radula of each species, its characters, in connection
with the conchological ones, are favorable to the specific distinctness of the two forms.

The depth at which the specimens have been captured, makes a somewhat exceptional
appearance amongst the other species of the genus1); the specimens contain the soft parts and
so one may conclude that they will have lived on the collecting-ground.
The rhachidian tooth (R) of the radula has a broad, angular body, with a rounded basal
line, its cusp has one large median denticle and on each side four smaller ones; the lateral
tooth (1) has a rhombic shape with a taillike process on the distal side of the body and a long
cusp with four smaller ones on the visible distal side of the reflected margin; the uncini have
the family-character, the denticles of the outer ones are bifid and trihd.

According t<> Tryon the radula of this species is still unknown, and I am not aware that
it lias since been described. lts location amongst the Amphiperasidae has even been doubtfnl.
In an old radula of tliis species trom Amboina I see that by the characteristic mmblike uncini
the ^enus belongs without doubt to that family. The teeth of the central field are however
sufficiently different from its allies to consider the genus Calpurnus as a valid one. The rhachidian
tooth R has a broad body, with two wings near the base and a very large central cusp,
with one or two small denticles at its base. The laterals (1) have a subquadrangular body and
a very long archlike cusp, with a small denticle about halfway; these teeth are quite different
from those of other species of this family figured by Troschel.

Kiener (1. c), that from Stat. i is young and resembles the upper whorls of Kiener's fig. i ;
the specimens from Stat. 7 1 belong perhaps to var. turritus Lam. but are too young to be
quite certain about them; by comparing fig. O of Rumph, with the figure of Chemnitz, quoted
by Lamarck. for his var. turritus, I think v. Martens was wrong in identifying that fig. O
with the var. turritus. In the type the back view of the last whorl occupies at least half the
length of the shell, in the variety it is shorter, in Chemnitz's figure it scarcely surpasses a third
part of the length. Tryon's fig. 43 may still belong to the type of the species.

Both specimens are empty shells, they are very small, being only 29 and 321/:, Mill. in
length. They differ from the descriptions by the columella; which is wrinkled in its whole length
instead of being only wrinkled above and below, but as these wrinkles are less conspicuous in
the specimen from unknown locality, I suppose this character may have but little value. By
these wrinkles the shells are allied to 5. deformis (Gray in Griffith's Animal Kingdom,
Vol. XII, pi. 25, fig. 5), but the shape of the apertural wing agrees with that of S. labiosus;
the Siboga-specimens are in some degree intermediate between the two species.

The specimen from Stat. 133 agrees very well with Reeve's figure but it is smaller and less
intensely coloured, that from Stat. 279 is still smaller and has a basal row of obtuse tubercles,
the third from Stat. 313 is young, this latter specimen has some resemblance with the species
of the deutatus-group, but I cannot conceive how Tryon considers this species to be a variety of
S. dentatus, as it is very conspicuously winged ; the observation of Reeve, that many specimens
of 5. labiosus are nearly allied, fully agrees with the specimen from Stat. 133. Unfortunately
none of the specimens contained the soft parts.

The specimens are very variable in shape, size and colour, also in colour of the columella
which is as in the quoted fïgures blackish, more or less deep orange or white. In employing
the name muricatus for this species, I have foliowed Boog Watson (l.c.) though it is generally
known as 5. urceus. But the reasons of that author for changing the name, seem to be too
convincing, to neglect them. Hedley (Proc. Linn. Soc. New South Wales, 1904, p. 188) applies
the name 5. ustulatus Schumacher for this species; this name is however of more recent date.

This is the species better known as 5". floridus Lam., which after Haxlkv (cfr. Boog
ought to bear the Linnean name of S. urceus. Linnë" himself quotes fig. T of
RtMi'ii. which is certainly not Lamarck's floridus, but probably S. dentatus Lin. if not S. nncri-
catus Martini; as the fig. G of plate 32 of GuALTIERl (Index testarum conchyliorum), likewise
quoted by Linné, is however quite another species of Strombus, the original specimen is the
only safe source, and so this shell must bear the name urceus, hovv inconvenient it may be to
alter long familiar names.

This fine shell has much puzzled me; after comparing it carefully with typical specimens,
I can see nothing in it but a dwarfed form with obsolete sculpture, probably owing its peculiar
character to the considerably greater depth. A young specimen is scarcely different from young
ones from Stat. 306. Unfortunately the shells contained nothing but some mud.
The radula of a small specimen from Stat. 306 agrees in many respects with those of
other Strombidae, it is short, with about 35 rows of teeth, its colour is yellowish. The rhachidian
tooth (R) has a body which is broad in front and suddenly narrower about halfway; its cusp
has 1 1 denticles, of which the central one is the largest; the lateral tooth (1) has a transversely
much elongated body and about 9 denticles on its reflected margin. The uncini (U) are long,
slender, much curved, with a few small denticles on the sides. It was a male specimen with
a long slender penis, ending in a thickened, spear-shaped point.

I have maintained Rimella as a genus, though it has been considered by Fischer and
Tryon as a subgenus of Rostellaria, but the operculum is serrate as in Strombus, instead of
being smooth-margined as in Rostellaria.
The forma minor distinguishes itself by its smallness and the vivid painting, the specimen
from Amboina which has a length of 26 Mill. and which is also more gayly coloured may be
considered as a link between the type and forma minor.

Ili is species is also very variable in size, the smallest specimen from Stat. 4 being only
14 Mill. in length, the largvst from the same locality 23 Mill., this latter being only surpassed
bv a specimen from Stat. : measuring 25 Mill. The opercuium is serrate, as in A'. cancellata\
,i> far as 1 know this species has not been figured before.
The radula which, as far as I am aware, was not yet known is very small, its length
is about k, its breadth '/s 0I" a Mill., with about 35 transverse rows. The rhachidian tooth (R)
is broadly rounded in front, contracted behind, with a cusp bearing one moderately large central
denticle and about 6 smaller ones on each side, the laterals(i) are strongly transversely elongate
with a simple reflected margin, terminating in a sharp point towards the centre of the radula,
the uncini I are long and slender, strongly curved, with a few indistinct denticles. The general
appearance of the radula is much the same as that of the preceding genus, as far as may be
judged from one radula of each, the chief difference being the smooth margin of the laterals,
which are provided with many denticles in Rostellaria.

Of the two specimens, one is characteristic, being white with a broad brown band at the
base of each whorl, it seems to ditfer from the figures by one or two of the spirals being
slightly prominent, in the other specimen I see a few brown spots on the base of the whorls,
but no distinct band, and two spirals so much developed as to form one row of small tubercles
on the upper whorls, about halfway, and a second row, nearly concealed by the suture. Both
specimens an- young. If adult they might be described as a variety, but now I prefer to make
only mention of these characters, as constituting individual aberrations of the type.

Very variable in colour, yellowish, brown, whitish, often more or less banded and variegated
with darker colours, however shape, size and sculpture agree with such specimens as may be
considered to belong to the type. Cerithium rubus of Martyn, seems to be quite another
species; according to Pilsbry (Proc. Acad. Nat. Sc. Philadelphia. 1901, p. 392) it should be the
same as C. echinatum of Lamarck; if this be right; the species recorded above sub N" 4,
ought to bear that name.

According to Reeve, the only difference between C. aduncum and dorsuosum should be,
that in the former the outer lip is ridged, bein^ smooth in dorsuosum. Now, as the very old
specimens from the above locality have the outer lip smooth, the younger ones have it ridged,
with everv grade between them, I think they ought to be united, as for the lirst time has been
done by Tryon, afterwards by Kobelt on Tryon's authority; the "Siboga'-specimens are less
humped, than the figure of aduncum, the colour also agrees with Reeve's dorsuosum, but in
size and in sliape of upper whorls, they come nearer to his aduncum.

Though the specimens have a fourth row of nodules on each whorl, in contradiction to
the original description of Adams, who says "triseriatim granosis", they belong no doubt to the
species under consideration, as they have been compared with the types in the British Museum
by Mr. E. A. Smith; the shell has a tendency t" be banded with fulvous above the suture,
the fourth series of nodules is smaller and so may have been overlooked, moreover I see a
• rmediate lirae especially on the last whorl. There is a single varix on the left side of
the bodywhorl and another bordering the aperture externally; the whole shell is covered with
l ae, only visible under a strong lens.

I cannot separate this form from the subfossil ones from Celebes. The sculpture of these
latter seems to be sharper, but this may depend on its fossil state or on local influence. The
recent specimens are dark yellowish-brown, mottled with white, mixed with irregular patches of
crimson on the last whorl ; the aperture especially the columella and canal is stained by the
same colour.

Shell elongate, yellowish-brown, with many convex whorls. Nucleus wanting, remaining
whorls 12, the uppermost closed by a calcareous septum, upper ones regularly convex, lower
ones with a broad excavation below the suture, which is not deep, slightly compressed at the
sides. Of the two specimens (which are unfortunately not adult) the largest has 4 varices on
the lower whorls. Sculpture consisting of 5 spiral cords, of which one borders the base of each
whorl, the uppermost bordering the subsutural excavation. The whole shell, as well the spiral
55

cords as tin- interstices and the excavation, is covered with regular spiral rows of smal! granules,
giving t<> man) parts .1 cancellated appearance, one could as well say thal in the upper whorls,
the shell is cancellated by granular spirals and concentric riblike striae; moreover the shell lias
on the lower whorl iall) of the smaller specimen, indistinct ribs; last whorl carinated by
the strong peripheral cord, it^ basal pan with two stronger and a great number of finer spiral
cords or lira ed bj very fine growthstriae. Aperture subquadrangular, its characters cannot
t. by the juvénile state; the right margin, which will most probably lx- varicose in
the adult shell, is still thin, columellar margin curved, terminating in a sin ui canal, directed
towards the left and slightly upturned.
This new species is very peculiar by its shape and sculpture. I know no species to
which it may be allied and think, if it were adult, it would prove to constitute a new section.

Kobelt, whose figures are not very characteristic, especially not in the shape of the canal,
says: " Aus dem indopacifischen Ocean ist sie meines Wissens noch nicht bekannt geworden,
wenn nicht etwa Cerithium graniferum Pease hierher gehort". Dunker (Index Molluscorum
maris Japonici, p. 108) has recorded the species from Japan, and has observed specimens with
brown lines in the interstices of the lirae, more rarely whitish ones, agreeing with Philippi's
figures. Previous to this record is that of Lischke (Japanische Meeres-Conchylien, Band I p. 72,
Band III p. 49); v. Martens (Moll. Mauritius p. 280) quoted by Kobelt, prefixes an "I" to
the species, meaning that it lives also in the Indian Ocean (Nicobaren, Ceylon, Malaischer
Archipel). In the majority of the specimens, the interstices of the lirae have distinct brown lines,
where they are wanting, this seems to be caused by fading, in dead specimens. The canal, if
intact, is by no means so straight as in Kobelt's figures, so I have left the species in the
genus Clava = ]Tcrtagus.

I'his species lias been ascribed both to Vertagus (= Clava) and Ceritkium. Dunker
himself and Tryon, describe it as I 'er/agus, Kobei.t and Watson (Challenger-Gastropoda) as
Cerithium. Pilsbry, who in his "Catalogue of the marine Mollusks of Japan, 1895, p. 56,
enumerates it as Clava Pfefferi, says in 1901 (Proc. Acad. Nat. Sciences, Philadelphia, p. 393)
■ rhe Vertagus Pfefferi of Dunker is not a Vertagus or Clava, but a true Cerithium". The
' Siboga" -specimens agree in every partioular with the original figure and description of Dunker,
bnt if one looks into the apertnre in an oblique direction, one sees a more or less distinct fold on
the cohunellar side, which is very strong in young and broken specimens, if one looks however
at the adult shell en face, the fold is not visible at all. The species varies not only in colour,
at has been stated by DUNKER, bnt also considerably in size.

Shell small, turriculate, brown, with about 10 postnuclear, flat whorls, the nuclear ones
wanting; each whorl with three spiral ribs, of which the upper and basal ones are thick, the
median one is narrower, the interstices are wider than the ribs, distinctly radiately striate; on the
last whorl the number of spiral ribs amounts to five, two ribs appearing below the peripheral one :
moreover two small intermediate striae appear towards the aperture. Suture not conspicuous.
Aperture subquadrangular, right margin straight, simple, but not sharp ; columellar margin
smooth, with a rather thick layer of enamel, upper corner of the aperture with an entering
rib, formed by a continuation of the most basal of the lirae, canal short, rather wide, directed
towards the left.
Alt. 51/,, lat. 2 Mill.
This small species may be allied to C. dextroversa Ads., by its sculpture consisting of
3 carinae of which the central one is smaller, but that species is whitish, much larger and has
a larger number of whorls, for even if complete, the new species scarcely could have more
than 1 2 whorls.

Part of the specimens is slightly larger than the type described by Melvill and Standen,
moreover they are more or less variegated with brown. The operculum is rounded-oval, with
many whorls, I think about 8, of which the outer ones are broad, the central ones so small
that I cannot count them with accuracy.
The radula is exceedingly small and of difficult observation, its breadth being scarcely 1/G
of a Mill., its length could not be ascertained, as it feil to pieces, but it may not have exceeded
72 Mill. The rhachidian tooth (R) has a broad, subquadrangular shape, with curved sides, the
cusp has one larger denticle and three smaller ones on each side, it seems that along the
basal margin, runs a narrow very indistinct zone, but by the excessive thinness, I am not quite
certain about this, the laterals (1) have an elongately subrhombical shape, the cusp has one

- denticle and one proximal, 5 distal, smaller ones, the uncini (U are very slender, rather
long and considerably curved, one of the two rows seems to 1»- verj indistinctly denticulate

et a sep s, the rhachidian and lateral teeth resemble in several particulars the rïgures
of radulae of I ithiopsis and Litiopa by Tkiwiim iCiebiss der Sclinecken PI. XI,
fig. \i and ij l>nt the uncini seem to be more slender and are distinctly denticulate in these
1 Argyropeza, the denticles, if they exist at all, are very faint. The operculum
n described by Fisi her (Manuel de Conchyliologie) as suboval, paucispiral,
with sublateral nucleus, placed at the left side of the aperture, that of Litiopa as oval, very
thin, paucispiral. with subterminal nucleus. As stated above the operculum in Argyropeza is
multispiral and has a subcentral nucleus. From Bit Hum, of which 1 find no description
the radula, it should be distinguished by its many-whorled operculum.

Shell small, pyramidal, white, whorls 1 1 '/,, of which nearly 2 form the nucleus. the first
is rather bulbous and smooth, the second radiately ribbed one is also swollen; remaining whorls
regularly increasing, slightly contracted above and below, nearly straight towards the middle,
with two spiral rows of pointed nodules, connected by slight spirals and oblique radiating ribs,
moreover the shell has a thin spiral, just above the linear suture. The rest of the surface is
smooth and shining, with a slight nacreous lustre and with numerous fine growth-striae. Body-
whorl conspicuously keeled below the periphery and with a second keel at some distance on
the smooth base. Aperture subrhombic, outer margin thin, angulate at the end of the lower
row of nodules, columellar margin rounded, slightly curved, ending in a point, where it joins
the basal margin.

This species has much puzzled me, more than once I had compared it with the preceding
one, but the very different nucleus and the aperture abstained me from considering it as belonging
to the genus Argyropeza, unfortunately the operculum and the soft parts are wanting; at last
I asked the assistance of Mr. J. CoSMO Melvill, who suggested it would be a Cerithopsoid
shell, probably belonging to the genus Argyropeza. As to the different nucleus, I found it had
much resemblance with that of Cerithium obeliscoides Jeffr. (Proc. Zool. Soc. Lond. 1885,
. PI. VI, fig. 4 . Jeffrevss (1. c. p. 59) divided the species of Cerithiopsis in two sections:
-A. typical with acuminated apex and B. Eumeta Mörch, Apex blunt". If the species nou under
consideration, really belongs to the genus Argyropeza, this genus could be divided in the same
inner. I have named it after one of the authors of the genus. The new species is larger,
with less convex whorls than A. divina, it has a nearly smooth base and quite
different nucleus.

Operculum paucispiral, with a subterminal nucleus on the left or columellar side.
The radula is rather long, about y1/i MUL in length; its rhachidian tooth (R) has a

broad, rounded, two clenticles on the body or basal part; lateral tooth (1) with apparently sub-
triangular body, with a long tail at the distal side, a large reflected cusp and 3 smaller denticles
on its distal side, probably also a few on the proximal side, which are however covered by
the central cusp; uncini (U), with an elongate body, the inner one has a cusp with 6 denticles,
moreover if placed in a favorable position, I see a very thin part along the body, ending in a

The specimen is very large, nearly 17 Mill., the length stated by Hinds (l.c.) being only

Shell rather large, conical, with slightly convex sides. Nuclear whorls wanting, remaining
ones about 12, concave, with two spirals, consisting of beads, the basal one the strongest,
between these two, but nearer to the upper one, runs a third spiral, which is much narrower
and not beaded but waved, at the shallow suture a tracé of a fourth spiral makes its appearance,
it is quite visible on the last whorl, where it proves to be less strong than the basal one of
former whorls, and to be less conspicuously beaded, it is accompanied by a fifth spiral, placed
at a small distance ; moreover the whorls are sculptured by perpendicular grooves and flat ribs,
connecting the beads of the upper and lower rows of beads, and finally the whole shell with
exception of the beads, is covered with microscopical spirals and radiating striae, which fill also
the space between the 5th liration and the canal, the base is also plicated by a few radiating
folds; the beads of the upper row on each whorl are constantly yellowish, those of the basal
row alternately (but not regularly) white and yellowish-brown, with occasionally brown spots
between them, the colour of the rest of the shell is of an ashy violet. Aperture subquadrate,
columellar margin thickened, with two small callosities, of which the lower one borders the
short canal, which is a little curved backwards.
Long. (incl. canal) 13, lat. 31/., Mill.
The specimen is slightly bleached by time, perhaps by the action of spirits. I know

The "Siboga"-specimen is smaller than the type, being only 16 Mill. in length, the

growth-striae, the keels of last whorl are sculptured by strong spirals, the shell is covered by
a thick, fibrous, yellowish-brown epidermis, with strong grooves, a few spinous fibres are visible
here and there on the keels. Aperture subcircular, but with many angles, of which one at the
upper part, three are formed by the keels, which are hollow interiorly, and one by a basal
channel. Columellar margin concave, interrupted by the basal keel, tortuous below, terminating
in a blunt point, joining the basal margin by the rounded basal channel, the columella is

This is a very remarkable species; amongst those described it has only a remote
resemblance with T. bicarinata Brod. and Sow. and T. coronata Gould, it differs however so
much from both, that it is not necessary to insist upon the differences. The three very strong,
hollow spiral keels are most characteristic. As to the generic position, the epidermis, shape of
aperture with basal channel and the operculum have guided me. As I would not destroy the
only specimen, I was unable to examine the radula.

I found in the same tube containing the former species, two smaller shells, both perhaps
young, which I could not identify even generically ; they have a superficial resemblance with
the new Trichotropis, by being turbinate, with a fibrous epidermis and three keels, but these
keels are much less sharp or conspicuous, and the chief difference consists in the aperture,
which is slightly angular but not channelled below, the number of whorls is about 4 of which
about i1/* form a rather large nucleus, and 2l/2 are depressed above, between the conspicuous
suture and the uppermost keel.

I sent the largest specimen to Mr. E. A. Smith, who was also in doubt about its syste-
matic position, so I have abstained myself from naming it.
The radula resembles more that of Crucióulum than of Trichotropis, the rhachidian
tooth (R) is subquadrangular, with a large multicuspidate cusp, I see 8 small denticles on each
side of the median one, the laterals (1) are subrhombic, with a long cusp with denticles on both
sides, about 8 on the distal side; the uncini (U) are elongate, with a few denticles near the
point. This latter character is not in accordance with what is known of Trichotropidae. (Should
it be possible that these small denticles have been overlooked? In - Trichotropis the teeth much
cover each other).

halfway the interspace between the upper and median liration; moreover the whole shell is
covered with much weaker striae, having the character of growth-striae and traces of more
remote spiral striae. Basal face subconvex, hut quite flat in the centre, with a shallow groove
between the peripheral keel and the first of the basal lirae, this space is rather smooth, though
crossed by plicae running from the peripheral spines in an oblique direction; the outermost of
the basal lirae, which is not broad, is foliowed by two similar ones, about as strong as their

them nearly doublé) being larger than the interstices, these lirae are connected by small radiating

This species has by its conical shape some resemblance with S. trispinosa Watson, but
that species is considerably smaller, with less distinct spines, which have more the character of
rounded tubcrcles, it has smooth interstices, without the conspicuous plications of the new
species. The circumstance that the base of the specimens of trispinosa which 1 could compare is
much smoother, seems to give no reliable distinguishing-character, at least Watson ("Challenger"-
p. 1 ioj says : "has some faint spirals". I have named the new species in honour of
Mr. J. (.'. Mi.i.vii.i., who has kindly sent me for comparison all his materials of this genus.
to the radula of this species, it is a very small and rather obscure object, and only
pieces, I could get an idea of the shape of the teeth, the uncini quite covering
lian rows, and crossing even the uncini of the opposite side. The rhachidian or median
subquadrate basal part, with rounded, convex posterior and less convex lateral
70
179
margins, it has a broad, triangular cusp, with one small median denticle and about 6 smaller
ones on each side; the laterals (i) one on each side, have a transversely triangular shape, with
an unarmed, arched upper and concave proximal and basal margin, with blunt points at the
proximal and distal extremities of the basal margin; on each side I see at least 3, but I suppose
there are 4 uncini (U) which are long, slender and strongly curved. Though this radula has
some resemblance with that of Aporrhais, like Verrill (Mollusca of the New England coast,
Transact. Connecticut Acad. of arts and sciences, Vol. VI, May 1884, p. 186 and 188) has stated,
and like his figure (1. c. pi. 31, fig. 14^) affirms, I cannot agree without doubt with his view
that it should be Taenioglossate, as the "Siboga"-specimen has a radula with at least 9 rows
of teeth and probably 11. The nacreous character of the shell agrees with the Rhipidoglossa,
and so does the larger number of uncini. I should think the genus will belong to the Rhipi-
doglossa with a restricted number of teeth, such as Basilissa. As however only a knowledge
of other anatomical particulars, the position and structure of the gills, of the heart etc. can
decide the question I have left the family near Trichotropis, in accordance with the newest
systematic arrangement of Pelseneer (A treatise on Zoology, edited by Ray Lankester, Part V,

Shell rather small, spire forming a short gradate cone, umbilicate, whitish-yellow. Whorls
7, of which the uppermost forms the smooth nucleus, foliowed by about 2 whorls with a sub-
median keel and displaying a cancellated appearance by the intercrossing of subequal spiral and
radiating riblets. The other whorls have each 3 spirals, of which the uppermost runs at a little
distance from the suture, the next which is the strongest, renders the whorls carinate about
halfway, and a third which seems to run just in the rather conspicuous suture-, moreover the
interstices have more or less numerous fine spirals (numerous in the type, where they quite fill
the spaces) ; this spiral sculpture is crossed by radiating riblets, running straight in an oblique
direction, from the suture to the upper spiral, where they form small crenulations, in the next
interstice they are concave and at last convex towards the basal liration; last whorl rounded,
with a strong peripheral keel, being the basal one of the upper whorls, and a convex base,
with another spiral at some distance from the peripheral keel, and 1 2 basal spirals of which
three more spaced ones, at a larger distance from the subperipheral spiral, and 9 more central
spirals, which are flatter, at subequal distances, the innermost bordering the umbilicus; these
spirals are connected by small radiating riblets in the interstices, moreover these interstices are
filled, as far as I can see, with similar finer spirals as in the spire. Umbilicus moderately wide,
probably pervious, funnel-shaped, its wall with fine radiating striae and a conspicuous spiral
groove, terminating in a strong dentiform projection on the columellar margin. Aperture moderately
large, irregular in shape, with a rather deep sinus at the suture (about i1/, Mill, behind the

This description is made after the specimen from Stat. 178, which was the must complete
one, the "( ::^ slightly differ by the number and disposition of the basal spirals, and
more considi in the finer spirals of the interstices between the keels, which in some parts
rly wanting and are, for instance, reduced to 1 and 3 in the spaces below the infra-
sutural spiral and above the peripheral keel in the specimen from Stat. 88, as however all other
chara ire really the same, 1 think these ditïerences will prove to be individual. I maybringin
■mbrance what Dall says (Buil. Mus. Comp. Zool. Vol. XVIII, p. 269), dealing on Seguenzia:
-Hithcr each separate individual is to be regarded as a species, or the variability is very great.
Persistant study of the specimens has convinced me, that the latter is the true solution, and that
the most evident characters, such as the umbilicus (in some adult specimens) may be present
or absent, that the number of spiral threads, thcir strength and sharpness on the basal disk.
are entirely inconstant".
This species seems to be nearly allied to S. elegans Jeffr. (Proc. Roy. Soc. 1876, p. 200,
Proc. Zool. Soc. Lond. 1885, p. 42, PI. 5, fig. 1, ia) but the radiating sculpture in the new
species is much less crowded and coarser, the same is the case with the basal spirals, the new
species is less flattened below the suture, more conical etc. These ditïerences in specimens from
such a remote provenience, have induced me to consider them as specifically distinct.

at a little distance from the mouth, columellar margin connected to the outer one, by a thin
layer of enamel on the body-whorl, it is first strongly excavated above by a rather deep sinus,
reaching the columellar tooth, below this tooth it is again concave and terminates in an angle
when it joins the basal margin at the point terminating the umbilical keel.
Alt. 3, lat. 31/., ; apert. alt. i5/,., lat. i3/5, diam. of umbilicus about i Mill.
These measurements will be more or less altered in a specimen with complete aperture.
This new species has some resemblance with S. elegans Jeffr. but differs sufficiently by
the number of keels and by the aperture, which, though broken, has other characters, the
columella in elegans being much longer than it can be in a complete specimen of 5. Sykesi,
the whole shape of S. elegans is consequently more obliquely elongate, the sculpture is much less
developed in the new species. It has also resemblance with 5. polita Verco (Trans, and Proc.
Roy. Soc. South Austr. Vol. 30, 1906, p. 222, PI. 9, fig. 3, 4, 5), especially in its sculpture,
but that species, according to Verco (1. c. PI. 9, fig. 5) is only rimate and the keels are blunt
and placed in a different manner. The nearest ally is .S'. tonica Wats. (Journ. Linn. Soc. Lond.
187S, Vol. 14, p. 589; " Challenger"-Gastrop. p. 107, PI. 7, fig. 3), and indeed I have been in
doubt if it should not be an oriental variety, but that species, as figured, is much more depressed,
has a more conspicuous liration at some distance from the suture, and the radiating sculpture
seems to be more conspicuous in 5. ionica.
Named in honour of Mr. E. R. Sykes, who has sent me for comparison a beautiful lot
of specimens of this genus.

Stat. 211. 5°4o'.7 S., i2o°45'.5 E. I!5§ M. Coarse grey sand. 1 Spec.
Shell rather small, conoidal, with a high spire and convex base, scalar, rimate, yellowish-
white. Whorls about 7, of which the upper one forms the smooth, bulbous nucleus, foliowed
by 2 whorls, which have a strong median keel and traces of a third one below the suture;
these lirations become more conspicuous on the lower whorls, which have the median keel,
another one just below the suture and in some parts traces of a third one, running entirely
or partly in the deep suture; moreover the whole shell is covered with microscopic, close-set,
spiral threads; this sculpture is crossed by conspicuous riblets, fainter on the upper whorls, very
strong on the lower ones, and by very fine growth-striae ; the riblets are not close-set and form
conspicuous spines below the suture of the lower whorls; when they cross the upper spiral, they
run obliquely from behind and are curved in the lower part of the space between the upper
and median keel, being concave below; below this median keel they are convex; on the last
whorl runs a third keel, which is crenulated by the ribs, this is also the case with the median
keel, though not so strong; at some distance from the third keel a fourth one makes its
appearance, this is a little fainter and less crenulate, the riblets between it and the third keel
being also weaker. The interspaces of the keels described above are conspicuously concave.
From the fourth keel untill the centre run 5 spirals, of which the distal one at a considerable

with large interspao d by riblets in very various direction. Umbilicus rather large, but
nearly closed by the columellar margin, leaving only ;i fissure. Aperture incomplete, a rather
id but not deep fissure at the upper part, rounded and turncd up behind; shape of aperture
subquadrangular, irregular by the terminations of the keels, columellar margin expanded towards
the left, formed by a deep, rounded sinus above and another narrower one below, with a
strong tooth between them, this tooth is strongly compressed, as if formed by pinching the
columellar margin,

outline is more convex and the elaborate sculpture is quite different, so I don't hesitate to
describe it as new.

From this Station a specimen has been collected, belonging to the rimatc species, it
differs from the preceding one by its l)roader, less conical shape and its very simple sculpture,
consisting, as far as I can see, of a strong median keel on the upper whorls, of a very weak
one at the upper suture and traces of a third one at the lower suture, which latter keel is
conspicuous on the last whorl, moreover very faint interstitial spiral striae, crossed by radiating,
threadlike striae. The nucleus and a great deal of the outer layer of the shell are wanting, its
beautiful nacreous inner layer being visible in many partS; in consequence the sculpture is only
visible on some small parts, as other parts have still suffered of corrosion; the columella and
umbilicus have the same character, as in the preceding species. The outer margin of the aperture
is quite defective, as well as the basal sculpture. In these circumstances I have not ventured
t.i name the species, nor have I accurately described it, though it will be probably new.

These specimens have much puzzled me, those from the two stations being considerably
different. That from Stat. 241 is more slender and lias a coarser sculpture, somewhat different
from the specimens collected at Stat. 137. The reasons that I have united them to the Atlantic
S. monocingulata are: the greal variability of that species, as already stateil by Dall in his
publication on the "Blake" Mollusca, quoted before in dealing with 5. Dautzenbergi\ the differences
74
i§3
in the figures at my disposal, and last not least, the specimens received for comparison of
Mr. Dautzenberg and of Mrs. J. C. Melvill and E. R. Sykes, the specimen from Stat. 241
more resembling the specimens of Dautzenberg and Sykes by its stronger, shorter, more remote,
concave riblets between the sutural and next keel, while the specimens from Stat. 137, of which
one is a beautiful shell containing the soft parts, better agrees with Mr. Melvill's specimens,
with weaker, longer, more crowded riblets in the same space, these riblets being nearly straight
and only curved in their basal part, in this respect more resembling S. ercmita Verrill (Trans.
Conn. Acad. Vol. VI, PI. 31, fig. 15); these latter specimens have the subsutural liration but
very little developed, much less so than in the specimens of Dautzenberg and part of those
of Sykes, which are slightly variable in this respect.
Fam. Vermetidae.
This family is perhaps the most disagreeable amongst Gastropods to deal with; the
extreme variability in the majority of the species and the often vague descriptions, render it
impossible in many cases, to make safe identifications, except in a few instances, if the species
have prominent characters. Many of the names applied below are more or less doubtful and not
a few specimens must remain without name. In vain I hoped that the keeper of the mollusca in
the British Museum, where the types of Mörch are preserved as far as I know, with his usual
kindness should give me assistance, but he wrote me he knew nothing about that family ; and
though " nothing" will probably be too strong an expression, I could not get the hoped for certainty.

The specimens agree rather well with the figures and descriptions of Reeve and Tryon
(1. c.) and also with the description of Mörch (Proc. Zool. Soc. Lond. 1860, p. 409), but neither
with the figure of Chenu: Illustrations conchyliologiques, Siliquaria, PI. 2, fig. 1, quoted by Mökch
nor with the description of that author (1. c. p. 2), who says a. o. : "coquille semitransparante,
tres lisse, avec la fissure inarticulée", instead of an articulated slit, closed behind, open near
the aperture, like Mörch, Reeve and Tryon have stated. Lamarck's description (1. c.) agrees
with that of Chenu, as may be stated by a copy of his diagnose: "S. testa contorta, parvula,
semipellucida, candida, laevissima, fissura inarticulata".
Vermetus Adanson.
This genus is still more perplexing than the former, as has been discussed by Tryon
in his introduction of the genus (Man. of Conch. Vol. VIII, p. 163). I have only been successful
in identifying two of the species and even not quite satisfactorely.

This common and widely spread species is very variable in many respects, and so I can
agree with the views of Tryon, who unites several species with it. I have however found no
specimens corresponding to T. fttsco-cincta Petit. The colour varies from nearly white (probably
bleached) to yellowish-brown and even uniformly rather dark brown, in which latter case the
brown sutural band is scarcely perceptible. The whorls are more or less convex; in most cases,
but not always, the upper whorls are flatter, the lower ones convex. The sculpture varies in
distinctness of the keels, which are more or less granular on one, two or on all the lirae, and
this only on the upper whorls or on the whole shell, with many intermediate stages; in conse-
quence it is impossible, with so many specimens as I could compare, to separate them in
different species, even the specimens from the same locality, are as variable as those from
different parts of the Archipelago.

The specimens from Stat. 47 and 311 are young and bleached, in consequence their
identification is not quite safe. The largest specimen from Stat. 164 is very characteristic, but
the violet colour of the base is wanting; the brown lines of the base are less numerous or
even nearly wanting in young specimens. It appears that if the figures of Kobelt, l.c. PI. 15,
et, they belong to some other species. This species seems to be variable, at
I have seen some specimens agreeing in man)- respects, but differing in other particulars-,
1 describe them as:

Differing hom the type in being more painteel with yellowish-brown. The spotted band
below the suture is broader-, base with six white lirae, with small brown spots; the interstices
of the lirae are spirally striate, as in the type.
Though at a first look differing considerably from the type, the sculpture is really the
same, so I have not ventured to describe a new species on the slight differences recorded
above. The majority of the specimens is still young.

10. Melania (Melanoides) salibabucnsis n. sp. PI. XII, fig. 8.
Stat. 133. Lake Telaga Bindu near Lirung, Salibabu-island. 24 Spec.
Shell pyramidal, dark olive, wlth faint purple-brown flames, especially on the upper whorls,
often completely wanting on the lower ones; strongly decollated, remaining whorls 3 to 4,
slightly convex near the median part, constricted below the sutures, which are very conspicuous.
Sculpture consisting of numerous growth-striae, of which several, at irregular distances are
stronger and nearly riblike, these striae are crossed by impressed spiral striae, which occupy
nearly the whole surface of the upper whorls (in younger specimens), leave the upper part of
the median whorls free and are restricted on the median part of last whorl, where the basal
part is smooth again. Aperture ovate with a rather sharp angle above, outer margin protracted
below, columellar margin with a strong layer of enamel, which is dark grey in its upper part,
white below, with a yellow tinge near the base and a black rim all around; base of aperture
broadly sinuous.
Alt. (of large specimen) 22, lat. 9; apert. alt. 9 Mill.
This species is allied to M. turriculus Lea and crepidinata Reeve, but the whorls are
much less convex tlian in the latter species, they better agree in this respect with M. turriculus
but in that species the base is striated, the aperture not so strongly sinuous. This latter character
may serve to distinguish the new species from its allies.

Shell small, conic-oval, solid, opaque: whorls about 6, slightly convex, separated by a

sculpture of subsequent whorls consisting of rather thin, straight ribs, about iS on the last
whorl, crossed by spiral ridges, of which there are 6 on the penultimate whorl and 11 on the
last one, the sixth running just in a channel above the suture-, this sculpture renders the shell
cancellated; moreover fine growth-striae make their appearance in the squares remaining in the
interstices of this sculpture. Of the brown spots the upper spiral row runs a little below the
suture, on the alternating ribs, and five fainter ones, on the basal part of last whorl. Aperture
rounded oval, slightly angular above, outer margin regularly curved, with a strong varix externally;
columellar margin reflected over the pillar and the base. Yarix adorned with two larger brown

e specimens are smaller than those described by Sykes, who calls the colour pale
lilac; this is scarcely applicable to the Siboga-specimens, but the strongly projected inner lip
which is sii characteristic for this species is distinctly present in one specimen, where its length
reaches nearlj Mill., in the other one, which is probably younger, this projection is still
very slight, but in nearly every other respect it agrees with the more typical one, so I don't

The specimens as usually, are very different in shape and colour, they are more or less
elevated and entirely white, more or less radiated with brown, or nearly entirely brown. The
specimens from a great depth (Stat. 9) are fixed on a much worn shell of a Gastropod, perhaps
a Tritonidea, from Stat. 78, on Strombus urceits Lin., from Stat. 225 on Terebra crenulata Lin.,
Stromö?is urceus Lin., from Saleyer on large spines of an Echinoderm, probably Acrocladia,
from Haingsisi on Cassis vibcx Lin. So it is conspicuous that they have no preference for any
group of shells, to fix themselves upon. I can detect no basal shell-plate, but especially the older
specimens have made conspicuous scars in the shells on which they live. One rather adult
specimen from Saleyer, has in accordance with its abode on a spine, a strongly compressed
shape. Some adult specimens have young ones on their backs.

The specimen from Stat. 5 1 , which is the most characteristic, was afhxed on Gyrineum

New Caledonia, by Crosse, Tryon (1. c.) records no other localities, so it may be new for
the archipelago.

The specimens from Stat. 12 are so numerous and often form small colonies, that it is
rly impossible to count them; the majority from Stat. 12 lias been dredged alive
on Xenophora pallidula Rve, on a dead Murex belonging to or allied to M. ternispina Lam..
other specimens from the same locality live on stones or fragments of very diversified shells; those
from Stat. 95 and 105 are dead shells, those from Stat. 139 are affixed on a dead Xenophora and
a young dead Rostellaria. The specimen from Stat. 164. which should have lived at a depth
of 32 M. is very flat and broad, but the sculpture, consisting of more or less irregular growth-
striae, and shape of spire agree with typical specimens. Mr. Smith to whom 1 had sent this
doubtful specimen, pronounced it to be: "probably a dilated variety of A. ltssa", the specimens
from Stat. 204, which are dead shells, are from not more than 94 M. Dr. Tim 1 1 (1. c.) was
the first to state that the species, according to its anatomy belongs to Hipponyx = Atnalthea.
Afterwards Mei.vill (1. c.) came to the same conclusion on other grounds, and Smith (Proc.
Mal. Soc. Lond. VII, p. 122) states in a note that Prof. Gwatkin found the radula nearest
that of Atnalthea. M11 viu. (1. c.) has erected the subgenus Malluvium for this smooth species
of Atnalthea. The Siboga-specimens have no brown colour in the interior of the shells, as far
as I could see in loosened ones.

A most variable species. I have identified the specimens as well as possible, with the
aid of the figures of Reeve's monograph. Only the specimen from Stat. 225 contains the soft
parts, the other ones are dead shells, which is especially of interest for the specimen from
Stat. 59, which probably will not have lived at that great depth.
2. Mitrularia costifera n. sp. PI. XII, fig. 11.
Stat. 116. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. 1 Spec.
Shell small, suborbicular, thin, depressedly convex, white; nucleus subcentral, but placed
a little at the posterior part, smooth, spiral; a zone around the nucleus is sculptured by fine
radiating striae, the remaining part of the surface is sculptured by strong radiating ribs, about
23 in number, separated by rather deep grooves or interstices, about as broad as the ribs; the
ribs project at the margin and make it conspicuously denticulate, they are slightly nodulous and
waved and are covered, as well as the interstices, with radiating striae. Interior of shell smooth,
slightly grooved by the ribs. Cup-shaped lamina much broken.
Long. 9, lat. 91/,, alt. 31/, Mill.
I am not at all proud of this new species, as it is slightly defective, part of the outer
shell and of the internal lamina wanting. Moreover I suppose it may be still rather young. As
I failed to identify it with any of the known species, I asked the opinion of Mr. E. A. Smith,
who has at his disposal the types of the numerous species described by Reeve ; the result
was that Mr. Smith declared it to be new. The most characteristic feature is the presence of
comparatively strong ribs, conspicuously surpassing the margin of the shell. The dorsal view
calls in mind some flat specimens of Amalthea couica Schuin.

The majority of the specimens has the umbilicus not quite closed, partly this may depend
on their juvenile state, but in many cases the specimens of the same size are variable in this
respect. Generally I have observed that the umbilicus is no reliable character in this genus,
that in the majority of young specimens, it exists in such species which have it closed when
adult, but that the period of being closed is not the same in one and the same species. As to
X. pallidula, Dunker (Index Molluscorum Maris Japonica, 1882, p. 123) has made the same
observation, he says: "at contra nostra specimina umbilico angusto perspicuo lamina quidem

the specimens perfectly agree with typical ones, received from Japan.

St.it. ; S., U7°28'.6E. Flores Sea. 521 M. Coral. 2 Spcc.
Shell larg hiform, more or less umbilicate, thin, yellowish-white ; whorls about 8,
nucleus smooth, quent whorls slightly convex, with irregular surface, lower ones sculptured
with diagonal, undulating wrinkles, which are moderately strong and are crossed by much feebier
growth-striae ; suture linear, undulate ; the upper surface with various objects agglutinated along
mture and at the peripheral keel of last whorl, these objects consist of small stones and shells,
which leave however a large part of the shell free, perhaps with exception of the upper whorls,
which seem to have been quite covered, but to have lost the foreign bodies. Last whorl sharply
carinated, with a rather broad margin, marked by a broacl, shallow canal on the upper surface;
base concave, chiefly by the declining border, nearly smooth, but marked under the lens with
faint growth-striae, which are strongly curved towards the distal zone, moreover very faintly
crispate. L'mbilicus in one specimen open, pervious, partly covered by the columellar margin, in
the other specimen it is closed by a thin lamina, leaving a pit, which is also partly overlapped
by the columella. Aperture large, oval, its free margin thin, arcuate, its columellar and basal
margins strongly curved, the columellar one thickened and reflected, a thin layer of enamel on
the body whorl connects the margins. Operculum corneous, thick, nucleus lateral, with a few
coarse and very close-set, undulating striae.
Alt. about 60, diam. 98; apert. lat. 67 Mill.
This species, by the sculpture of the base allied to X. pallidula Rve, has a much finer
sculpture, indeed it is nearly smooth, moreover it is considerably larger, the shape of the basal
surface is much more oval, the whorls are less convex, and much less covered by the foreign bodies,
which are mainly smaller, are placed more remote and consequently leave a larger part of the
lower whorls free. In this respect (if only seen from above) it has some resemblance with X. calcu-
lifera Rve., which has however more convex whorls and a totally different sculpture of the base.

20 Mill. In this juvenile state, the sculpture of the base, so conspicuous in adult ones, is nearly
wanting; it consists of short striae radiating from the umbilicus, crosseel by a few (3 or 4) spirals
and leaving a large part smooth, unless for very faint, curved, growth-striae, a little more
conspicuous at intervals. The third specimen, though not large, is very characteristic.

The Siboga-specimen agrees in most parts with Sowerby's description and figure, but

I have foliowed the views of Philippi and other authors, in applying the name arach-
noidea for this species, this has been done in recent time by Hidalgo (Cat. de los Mol. Test.

it in liis Section B * Ventricoso-globosae ; operculo (in omnibus?) corneo". Tryon (l.c.) locates it
amongst the species with corneous operculum. As Menke lias not described his species 1 have
applied Bi unvtlle's name, which has priority, though he gives no more description thau Menke.
Perhaps the name lupinus of Deshayes (An. s. vert. Ed. 11, Vol. VIII, p. 648) will be the

Philippi has separated this form as a valid species. The Siboga-specimen exhibits all
ti 1 ters, but I think they are only vanetal. Tryon Man. of Conch. Vol. VIII, p. 21),
quotes it simply a^ a synonym. The specimen is about as small as Philippi's fig. S, and possesses
the fine, sulcated operculum.

different, I have applied the name given by Philippi to a shell with characteristic colour-pattern,
some specimens are partly of a brownish ground-colour.
10. Natica nebttlosa n. sp. PI. XIII, fig. 2.
Stat. 240. Banda. 9 — 45 M. Black sand, coral. 1 Spec.
Shell conically globose, thin, smooth, shining, with traces of a thin epidermis towards the
aperture; whorls 51/.-,, convex. The nuclear and part of subsequent whorls are nearly smooth,
but have a few radiating striae and the suture is bordered by a spiral ridge. The last 21/,
whorls are separated by a deep suture, with radiating striae, gathered puckerings below it.
Moreover the shell is covered with very fine growth-striae and a few scattered spirals, which
are only visible under a strong lens. Colour very light lilac, with a narrow white zone at the
suture, and a broader one round the umbilicus; the lilac zone of the shell has very faint rufous-
brown streaks, which are more or less waved, forming at the shoulder of last whorl, a row oi
arrowdieaded spots and a row of squarely-oblong blotches, just above the umbilical white zone.
Aperture oblong-ovate, rather angular at the upper corner; right margin thin, curved, columellar
margin nearly straight, but slightly concave, its upper part reflected on the body whorl, tongue-
shaped just above the umbilicus, of which only a small, deep pit of the upper part remains,
the umbilicus being nearly quite filled by a white, porcellaneous funiculum, with only a groove
at its left side, originating from the umbilical pit, becoming shallow towards the base. Oper-
culum calcareous, for a large part smooth and shining, near the nuclear part thickened by a
dull layer, bordered at the left by a comma-shaped rim ; right margin bordered by 3 raised
rims, of which the outermost is narrow and not strongly developed, especially towards the base
of the aperture; the median rim is rather narrow, much raised, bordered externally by a
shallow, internally by a deeper groove ; internal rim the broadest, separated from the rest of
the operculum by a, deeply incised groove.

Shell sniall. subglobose, with blunt spire, thick, shining, with rather strong growth-striae,
strongest below the suture, and microscopic waved spirals. Whorls 41/,, slightly convex, especially
the upper ones, which are separated by a conspicuous suture, which is shallower in the last
whorl : this suture strongly descends towards the aperture, and on this part the growth-striae
are very strong and crowded; just behind the aperture the shell is slightly contracted. Colour
white, with a large, irregular, yellowish-brown zone near the median part of last whorl, this
encloses irregular white spots. Aperture small, oval, with a blunt angle above; right
margin thick, curved, rounded below ; columellar margin nearly straight with a callous pad at
the upper part and a thick. subtriangular, porcellaneous deposit, forming in part the end of the
funiculum and covering the upper part of the umbilicus, which is narrow interiorly, hut apparently
pervious: a deeply incised rather broad groove, separates the funiculum from the bodywhorl,
o the columella joined to the thick, rounded basal margin of aperture by an angle which
produces a short tongue-shaped layer, just below the umbilical groove. Interior of aperture,
smooth, white.
Operculum wanting, luit the columella has a slight groove, indicating the presence of a
calcareous operculum.
Alt. 71/,, lat. 81/,; apert. alt. 5'/,, lat. 3 Mill.
This species may be recognized by its thick shell, by the strongly descendin^ suture,
the strong striae near the aperture, which is unusually small. I know no nearly allied specie-,.

Shell small, depressedly subglobose, with blunt spire; rather thick, smooth, whorls 3
one convex, the remaining nearly flat; sculpture consisting of very fine growth-striae,
: • ar the suture and towards the aperture. Colour yellowish-white, with a collar
104
of chestnut spots of an irregular shape, but having a tendency to be triangular below the suture
and on part of the penultimate whorl; these spots enclose irregular whitish spots. Aperture
oval, with rounded basal and outer margin, columellar margin nearly straight; upper angle of
aperture blunt, with a thick layer of enamel on the body whorl, forming a rim near the angle
of aperture and connected with the funicular tongue-shaped pad, which fills a large part of the
umbilicus, this latter seems to be pervious, and is formed below of a deep, large groove round
the funiculum, the whole columellar part is light chestnut (perhaps bleached).
Operculum wanting, probably calcareous.
Alt. 6, lat. 6-/.; apert. alt. 41/,, lat. 3 Mill.
This shell is remarkable for its brown columella and the blotches near the suture. It
may be allied to N. pseustes Watson (Challenger Gastrop. p. 44, PI. 27, fig. 3) but besides the
collar, I see no brown markings, as in that species and the umbilicus seems to be different, for
Watson describes it as disappearing behind the pillar callus, and I can introducé a fine needie
at a relatively considerable depth.

Shell conically globose, rather thin, smooth and shining. Whorls z,1/» moderately convex,
forming a rained spire. Sculpture consisting of very fine growth-striae, stronger towards the upper
suture of each whorl, crossed by microscopic, wavy, spiral striae. Colour of shell light yellowish-
redbrown, with a narrow white zone below the suture, and a large one occupying the base.
Suture of last whorl gradually descending towards the aperture, upper margin of last whorl
appressed on the bodywhorl. Aperture ovate, with a blunt angle above, right margin regularly
curved, more rounded below and passing imperceptibly into the basal margin ; columellar margin
nearly straight, with a porcellaneous pad above on the bodywhorl, slightly reflected over the
umbilicus, which is rather large, pervious, with scarcely any tracé of a funiculum, consequently
the columellar margin is only inconspicuously thickened, on the place where the funiculum should
terminate. Interior of aperture brownish.
Operculum wanting, probably calcareous, for the columella has a slight ridge.
Alt. 141/,, lat. 14; apert. alt. io1/,, lat. 7.
This species is of a very simple character, in its umbilicus it resembles N. semisukata

and colour. The locality recorded by the authors quoted above is New-Ireland. The specimens
from Stat. 37 and 64 are still more bleached, the violet colour being only perceptible on the spire.

The specimen from Stat. 258 differs from the type, by a third liration at the periphery
and finer sculpture of the base ; as the only specimen is not yet adult and the sculpture is also
variable in the typical specimens, I have provisionally considered it as a variety or individual
aberration. From T. ccrdalcum Melv. (Ann. and Mag. Nat. Hist. Ser. 7, Vol. XII, 1903, p. 297,

prominence of one of the spirals, of which there are 6 on the penultimate whorl, these spirals
are separated by narrow, shallow grooves and crossed by oblique striae or grooves, which
render the spirals crenulate, moreover finer spiral striae, more clearly visible in the interstices,
and fine growth-striae cross each other. The fifth of the spirals, counted from above is the
most prominent one. Base moderately convex, with 9 spirals, of which the inlVaperipheral 2 are

lirae, 8 in number on the last whorls; the infrasutural, the fifth and seventh spirals are more
prominent and stronger than the rest; these lirae are crossed by very fine growth-striae and
by moderately fine ribs, rendering the lirae crenulate in crossing them, the fifth is even tuber-
culiferous in some parts; periphery strongly keeled; keel wavy or denticulate by distant short
spines, the spaces between them crenulate; keel flat above, concave below, the rest of base
convex untill the umbilicus; base inclusive of the under surface of the keel, sculptured by fine
spiral lirae of which the innermost 4 are stronger and granular, especially the spiral bordering
the umbilicus, which is tuberculate, the whole base is crossed by radiating striae rendering even
the finer lirae crenulate. Umbilicus very large, occupying more than half the diameter, open,
leaving the volutions visible, each whorl has a row of large granules along the lower suture
and 2 a 3 finer ones crossed by radiating striae. Aperture much broken, probably circular,
containing the characteristic operculum.

This remarkable mollusk, which is not allied to any species I know, was unfortunately

I have provisionally left it in company with the other t y p i c a 1 species.

whorl. Aperture oval, with a thick, continuous, white lip, slightly refiected over, but not closing
the umbilicus. Interior of aperture flesh-coloured, white towards the margin.
Alt. 88/4, lat. 41/,; apert. alt. 3, lat. 21/. MUI.
This fine species may be allied to 5. clementina Grat., and bulbulus Sow. but is more
elongate and easily recognized by its violaceous colour.
8. Scala fragilissima n. sp. PI. XV, fig. 3.
Stat. 17S. 2°4o'S., I23°37'.5E. Ceram Sea. S35 M. Blue mud. 2 Spec.
Shell subperforate, pyramidal, very thin, transparent, yellowish-white, nucleus wanting,
remaining whorls probably 7 or 8 (both specimens incomplete), very convex, obtusely angular
a little above the periphery, with a very deep suture ; sculpture consisting of spiral ribs, about
1 5 in number on the penultimate whorl, and thin, undulating ribs, crossing the spirals and
giving a cancellated appearance to the shell ; these radiating ribs are, if well preserved, delicately
spinose at the upper part and their crest as well as the whole rib is undulated, these undulations
corresponding to the spiral ribs; the ribs are subequal, becoming only a little stronger with
age, their number is about 23 on the last whorl, which is slightly angular, but has no basal
rib. Aperture incomplete, probably nearly circular, only faintly angular above, its right margin
thin (youngr), its columellar margin slightly refiected over and nearly covering the umbilicus,
which in the largest specimen is still circumscribed by a thin rim.
Alt. (of largest specimen) g7/K, lat. 33/4; apert. lat. 2 MUI.
Though the specimens are rather incomplete, I think they are characteristic enough, to
deserve a name and description ; they resemble in shape 5". formosissima, from the Azores, but
have still much more convex whorls and much finer and more elaborate sculpture; in this respect
they resemble 5. undulatissima Sow., but that species is only very minutely spirally striate and
much broader in proportion to its length.

Stat. 51. Madura-bay. 69 — 91 M. Fine grey sand, coarse sand with shells and stones. 1 Spec.
As stated by Tryon, the figure and description of Reeve don't correspond; the figures
ol 5. pulcherrima and S. catanuensis having been changed on the plate. Clessin, whose
117
monograph seems \<> 1"- in most instances a bad copy and translation of that of Reeve, has
overlooked that mistake.
10. Sm/a 'a n. sp. PI. XV, fig. 2.
Stat. '.( S., 1 18 15'.2E. I M. Fine grey mud. 2 Spec.
Shell subperforate, pyramidal, thin, whitish; nucleus wanting, remaining whorls 8, very
convex, obtusely angular at the shoulder, slightly disunited, nearly smooth, but with a few
te spiral striae and fine growth-striae; the whorls are crossed by thin, slightly reflected
in number on the last whorl; these ribs are spinous at the shoulder, their margin is
serrulate serrulations may be natural or caused by friction) they are practically equal,
none of them being varix-like; base of shell regularly rounded. Aperture circular, right margin
thin (young? it> columellar margin broadly reflected over the perforation and (pjite covering,
but probably not closing it.
Alt. 141/.-. bit. 5 Mill.; aperture of a specimen long 9'/-, Mill., 21/., Mill.
This species resembles in shape the preceding one, but it is quite different by its nearly
smooth interstices of the ribs, which are themselves more simple, being undulate in S. fragilissima.
11. Scala Clathrus) Melvilli n. sp. PI. X1Y, fig. 9.
Stat. 114. Kwandang-bay-entrance. 75 M. Hard sand, very line. 1 Spec.
Shell pyramidal. imperforate, very thin, transparent, white. Whorls 9, of which 3 smooth
nuclear ones. Postnuclear whorls very convex, slightly shouldered, with a very deep suture ;
upper and basal part of each whorl smooth, median part with 3 thin spiral ribs in the inter-
stices of the radiating ribs, which are thin, lamellose, flexuous, with an auricle at the suture
and another at the shoulder, moreover an undulation at the peripheral part, and a second one
near the base of each whorl; in the upper whorls the ribs are more simple. Aperture circular,
with a broadly expanded margin, formed by the last rib, of which there are 15 on the last
whorl; columellar margin narrowly reflected, accompanied at the place of the umbilicus by a
lamellose rim.
Alt. 5' . lat. y ; apert, i1/, .Mill. in diameter.
This species resembles .S". malcolmensis Melvill (Memoirs and Proc. Manch. Lit. and Phil.
Soc. Vol. 42, 1S9S, p. 20, PI. 7, lig. 21. but the ribs of the new species are much more elaborate,
being flexuous.

it is very perplexing to see how the opinion of authors differs in the appreciation of the
limits of the species or varieties more or less allied to S. lamellosa. I have foliowed Messrs.
Melvill and Standen (Proc. Zool. Soc. Lond. 1901, p. 356), who have made use of the
familiar name lamellosa, Mr. Melvill being in 1903 still of the same opinion (Journ. of Conch.
Vol. 10, p. 348).
13. Scala (Op al ia) sp.?
Stat. 45. 7°24'S., u8°i5'.2E. Flores Sea. 794 M. Fine grey mud. 1 Spec.
This species may be new, but it is though large (nearly 20 Mill. in length), too much
worn, with broken aperture, consequently not recognizable, so I thought it better not to describe
a species, without a knowledge of the true colour, of sculpture and aperture.
14. Scala (Opalia) hutnerosa n. sp. PI. XIV, fig. 7.
Stat. 241. 2°24'.3S., I29°49'.3 E. Banda Sea. 1570 M. Dark sand with small stones. 1 Spec.
Shell elongately pyramidal, imperforate, moderately thin, white; nucleus wanting; remaining
whorls 11, convex, slightly contracted below the deep suture, there shouldered or angular;
sculpture consisting of low spiral ridges, about 1 3 on last whorl, of which the basal one forms
the rib characteristic for the subgenus, a small space above that rib and a larger one below
the suture are free of ridges ; the whorls are crossed by strong ribs, 1 3 in number on the last
whorl, not quite reaching the upper suture; these ribs are angular at the shoulder and less so
below, they are crossed by the ridges, which are however less sharp on the ribs, perhaps on
account of friction ; the interstices have fine, hairlike, elevated striae, which are also present on
the sides of the ribs. Base with traces of ridges and with the hairlike striae, but in a much
fainter degree. Aperture subcircular, slightly angular above, below and fainter at the end of
the shoulder and of the basal rib. Columellar margin reflected over the umbilical region, outer
margin thin (juveniler).
Alt. 15, lat. 41/,.,; apert. alt. 21/*, lat. 2 Mill.
I know no described species of Opalia, to which this new form is allied.

Stat. 159. o°59'.iS., I29°48'.8E. Halmahera Sea. 411 M. Coarse sand. 1 Spec.
Shell elongately pyramidal, imperforate, solid, corneous; nucleus wanting; remaining whorls
io1/.,, convex, with a deep suture, slightly shouldered; sculpture consisting of 3 strong spiral
ridges and a few spiral striae in the interstices, crossed by strong ribs, 12 on last whorl, angular
above, when the upper spiral crosses the ribs, being slightly nodulous by the intercrossing of
the strong spirals; some of the ribs have the appearance of varices, a. o. that next the aperture;
last whorl with 4 spirals, of which one is the usual basal one; base with a few very faint
spirals; the whole shell, especially the base is covered with very fine growth-striae. Aperture

Shell small, pyramidal, imperforate, solid, white: nucleus wanting; remaining whorls 7
moderately convex, with a distinct but no deep suture; sculpture consisting of impressed spiral
striae and fine radiating ones over the whole surface, if not rubbed of; ribs strong, thick,
ed by the spiral striae. ten on last whorl; the last very thick rib bordering the aperture.
il rib of last whorl strong; base slightly excavated, sculptured with faint spiral striae, crossed
bj the growth-striae. Aperture circular with a nearly smooth, rather thick internal lip. bordi
on the right and part of basal margin, by a broadly expanded flat varix, with the same
sculpture of the outer surface of shell.
Alt. 61/,, lat. incl. perist. V ,: diam. of apert. i'/,; Mill.
I know no species allied to this beautifully sculptured shell.
17. Scala (Cirsotrema) sp.
Stat. 153. o°3'.8N., I30°22'.3E. North off Waigeu-island. 141 M. Fine and coarse sand with
dead shells. 2 Spec.
Both specimens are young, they have some resemblance with the upper whorls of S.
Kieneri Tap. Can. but are different in their sculpture, which is very fine; as even the apertures
are incomplete, I have abstained myself from naming and describing them, though they probably
ng to a new species.

SUPPLEMENT.
Some sheets of the second part of this publication had been printed, when I received a
box of shells, found amongst corals of the "Siboga" materials; though this box contained only
common species, there were a few not yet enumerated in the first two parts on Gastropoda.
I have mentioned them in this supplementary note, and added a few localities of species already
dealed with, but I have omitted to mention such cases, when I found one or a few specimens
of species recorded in the bulk of the work, from the same localities.
